It is a circular concrete gravity structure, 140 m in diameter at its base, with seven concentric walls of stepped heights intersected by radial walls at 45-degree angles. A 14 m wide central shaft is surrounded by a breakwater wall ("Jarlin Wall") 45 m in diameter and 1.6 m thick pierced with 1.5m diameter holes. Between these two walls drill slots are arranged for drilling up to 42 wells.
Originally operated by Chevron Petroleum (UK), a division of Chevron, it is currently operated by CNR International.
